Generate .apk file with a WebView that shows my Webhosted PWA

I was looking for a simple solution to generate a .apk file with a webview that opens my PWA. (Because there is still no option to add a PWA to App and Play -Store.

The documentation was telling any about generating PWA. Now i realize that this means only that the code can be extended with .webmanifest and ServiceWorker… So is there any Tutorial that explain me, how i can create a .apk file that simply shows my PWA?
